Apart from conventional treatment, dentists are increasingly relying on physical therapy modalities in their clinical practice. The aim of this literature review is to analyze the clinical relevance and potential uses of ozone in modern dentistry. The research question is geared towards detailing the multiple potential applications of ozone therapy in a range of dental specialties. Based on the available literature, accessed via the PubMed, Google Scholar, Scopus, and EBSCO databases, a detailed search of the electronic literature was performed for 2001-2022. Eligible studies were chosen according to inclusion and exclusion criteria, using keywords: ozone, ozone therapy, therapeutic applications, oxidants, dental disinfectants, oral medicine, physical therapy in dentistry. Out of 834 manuscripts, 273 studies were curated. A total of 70 publications were used in the final consideration. After assessing their quality, they were analyzed to determine the relevance and potential use of ozone in the various aspects of modern dentistry. Ozone therapy is used mainly as an adjunct to the primary clinical or pharmacological treatment. In some cases of oral mucosal disease, it has proven effective as a primary therapy. During the literature analysis, it was noted that ozone therapy in dentistry is a subject of ongoing research, and the results are not always consistent. The multitude of studies in the literature on the applications of ozone in dentistry reflects the search for its undiscovered physical therapeutic potential.

Specialty-based practice is a fundamental component of US medicine and dentistry, yet the recognition of new dental specialties has markedly diminished in the past 50 years while medical specialization has flourished.
This article reviews the history of specialty development while focusing on the underlying scientific, educational, and cultural changes in both professions. The process of dental specialty recognition is also examined.
The current dental specialty recognition process provides a set of criteria aspiring specialties need to fulfill at the time of application, yet the relationship between the criteria and the sequence for attaining them is undefined. Scientific development and evidence-based practice have grown to become the cornerstone of contemporary health care specialization.
A new paradigm for specialty and subspecialty development in dentistry is needed. A model is presented herein that recognizes scientific development as the basis for specialization and describes a formal, sequenced process for the development of emerging specialties and subspecialties.
This new paradigm for dental specialty recognition builds on the current criteria for specialization while encouraging cross-disciplinary interaction and nurturing the development of emerging specialties and subspecialties in dentistry. Doing so will allow dentistry to maintain its lead role in the maintenance of oral health and oral disease treatment in the US population.

Short-term orthodontics (STO) serves to align anterior teeth. It has become popular in cosmetic dentistry as an alternative to destructive veneers and lengthy conventional orthodontics. The aim of this article is to raise awareness of the clinical limitations of STO and highlight some of the difficulties encountered with orthodontic retention. It also gives an overview of accredited training available to dentists who wish to develop their orthodontic skills. Clinical relevance: Greater awareness of the clinical limitations of short-term orthodontics will aid GDPs in appropriately selecting their cases and obtaining informed consent from patients. In addition, the article serves as encouragement for those GDPs wishing to develop their orthodontic skills and pursue further accredited training.

We review papers on diseases of the salivary glands published in journals relating to the head and neck, which are commonly read by members of our specialty. Most of the papers focus on the investigation and treatment of diseases of the parotid gland, which reflects the relative prevalence of parotid lesions among salivary gland diseases. Minimally invasive surgery is increasingly of interest. There is a lack of clinical trials that address the many controversies concerning salivary gland surgery, and much of the evidence for treatment is based on small case series and expert opinion, partly because of the relative rarity of salivary disease and the disparate groups that treat it. This problem could be addressed if regional and national oral and maxillofacial surgery (OMFS) units, and possibly other specialties, could collaborate more closely and combine data.

The periodontal pocket, one of the definitive signs of periodontal disease, is the most common parameter to be assessed by dental clinicians. Periodontal probes have been the instruments most commonly used to locate and measure these pockets. Regular use of periodontal probes in routine dental practice facilitates and increases the accuracy of the process of diagnosing the condition, formulating the treatment, and predicting the outcome of therapy. Advances in the field of periodontal probing have led to the development of probes that may help reduce errors in determining this parameter used to define the state of active periodontal disease. One such advance is the emergence of probes that purportedly assess periodontal disease activity noninvasively. The selection of periodontal probe depends on the type of dental practice: a general dental practitioner would require first- or second-generation probes, while third- through fifth-generation probes generally are used in academic and research institutions as well as specialty practices.

OBJECTIVE: Health policy in England is seeking to minimise hospital use and provide access to services in a primary healthcare setting and maximise skill-mix, driven by issues such as cost and access. The aim of this review was to determine the effectiveness of increased use of skill-mix and service transfer within general and oral healthcare. Secondary outcome measures were related to cost, quality, access, health outcomes and satisfaction.
METHODS: Data sources were the Cochrane Database of Systematic Reviews, Centre for Reviews and Dissemination DARE, British Nursing Index, CINAHL, EMBASE, MEDLINE, and PsycINFO from 1996 to August 2008. The reference lists of relevant papers were scanned to identify additional studies.
METHODS: A rapid appraisal of systematic reviews, randomised controlled trials, controlled trials and service evaluations in relation to specialist services, practitioners with a special interest, medical and dental, nursing and dental care professionals, together with evidence of service shifts from secondary to primary care was undertaken.
RESULTS: A total of 206 papers were reviewed. All titles and abstracts of articles and papers found were extracted and validated according to predefined criteria. They were screened for relevance by two researchers, who assessed trial quality and extracted data. Twenty-six papers met the inclusion criteria. The literature demonstrated limited evidence of the cost-effectiveness and health outcomes associated with changes in setting and skill-mix. However, there was evidence of improved access, patient and professional satisfaction.
CONCLUSIONS: There is an overwhelming need for well-designed interventions with robust evaluation to examine cost-effectiveness and benefits to patients and the health workforce.

OBJECTIVE: A peer review study was carried out to assess the written communication between consultants and specialist registrars in restorative dentistry with the referring general dental practitioners.
METHODS: Seven people took part in the study and each presented referral and reply letters for five patients whom they had seen for consultation. The referral letters were used for information only and were not used in the peer review process. Each participant inspected the referral and reply letters from the other six participants. The reply letters were anonymously peer reviewed by using a proforma containing agreed criteria in relation to appropriate factors to include in the reply letter. The reviewer also ranked the letter in relation to overall quality on a 1-10 point scale.
RESULTS: It was found that the participants\' letters generally conformed positively with the agreed criteria although there were some differences between individuals. There were particular problems identified in relation to tooth notation. Reply letters commonly used different forms of tooth notation to the referring practitioners.
CONCLUSIONS: The ranking of the letters generally indicated that the participants\' replies were judged to be favourable by their peers. There may be scope for continuing this study in relation to peer review by other groups of professionals, in particular practitioners in primary dental care.
